WIRE MATTRESS.

Specification of Letters Patent.

Patented Jan. 12, 1909.

Application filed February 13,1908. Serial No. 415,774.

To all whom. it may concern:

Be it known that I, GARY B. SMITH, a citizen of the United States,residing at Anoka, in the county of Anoka and State of Minnesota, haveinvented a new and useful ire Mattress, of which the following is aspecification.

This invention has relation to wire mattresses and it consists in thenovel construction and arrangement of its parts ashereinafter shown anddescribed.

The object of the invention is to provide a structure of the characterindicated consisting of a supporting frame having a series of continuousendless cables each formed into a chain of rhombic sections with theapices of the obtuse angles disposed longitudinally of .the same and theacute sides of the chain of sections passing within and engaging attheir apices similar'sides of the next adjacent chain of sections andvice versa. By such a.structure the continuous endless cables maintaintheir shape and relative arrangement for an indefinite length of time inas much as one cable engages the other at the apices of the acute sidesof the sections, consequently, the cable sections are not liable to pullor move with relation to each other and lose their rhombicconfiguration.

A further object of the invention is to provide apeculia'r and aneflicient means for joining the ends of the cables together wherebycontinuous cables are formed. The said means is so located as to bepractically concealed within the cable and upon a casual observationdoes not break or interfere with the continuous appearance of thetexture of the cable. Y

In the accompanying drawing: Figure 1 is a plan View of a mattress withparts broken away. Fig. 2 is a plan view of one form of means forconnectingthe ends of a cable together. Fig. 3 is a perspective View ofanother form of means for connecting the ends of a cable together, andFig. 4 is a sectional view of the form of means shown in F 2.

The mattress consists of the rectangular 3 frame 1 which is provided atsuitable intervalsalong its sides with the pegs or retainers 2. Thecables 3 are continuous and endless. That is to say, their ends arejoined together as will hereinafter appear. Each cable is formed into aseries of rhombic sections 4 which sections have the apices-of theobtuse angles disposed in alinement longitudinally of the chain and theacute sides of the chain section pass within and engage at their apicessimilar sides of the next adjacent chain of sections and vice versa asat points Thus the sections of one chain are connected with the sectionsof the next'adjacent chain at their acute angles and consequently theparts are so disposed as to brace each other with a decided tendencytoprevent the sections from losing their rhombic configuration. .The wirefabric '6 lies over the frame 1 and the cables 3.

Two forms of means are shown for the purpose ofeonnecting the ends ofthe cables 3 together to render the same continuous. in the orm shown inFig. 2 which is located at one of the acuminate ends of one of the rhombsections a wire 8 is inserted in the ends of the cable 3 so that theextremities of the said cable abut against each other or nearly so as at9. As the cable 3 is made up of a series of wires helically twistedtogether the said cable is hollow and will readily receive the wire 8.At the point 16 the wire 8 and the end portions of .the cable 3 aretwisted upon themselves which distorts the cable section slightly out ofits true rhombic configuration although it maintains such aconfiguration generally. The said twist 10 also binds the wire 8 in theend portions of the cable 3 but not directly at the extremities of theends thereof and a loop is formed as at 11 which may receive one of thepegs 2 or an acuminate end of an adjacent rhombic section.

In the form of means illustrated in Figs. 3 and 4 several wires 12 areinserted in the end portions of the cable 3 and the said wires 12 areattached to the inner sides of the wires 3 by means of'solder as at 13in Fig. 4. Several wires 12 are used in order to present sufiicientsurface for the solder to eflect-ually engage. In this form the twist l0and loop 11 shown .in Fig. 2 are dispensed with but in both of the formsof end connecting means the means for fixing the bonding wire or wireswith relation to the end portions of the cable are not located directlyat the extreme ends of the cable nor do they bridge from one of thecables to the other but are located at points remote or away from theends of the cable but at end portions of the same. By such means forconnectin the ends of the cable together the resiliency of the cable isnot detracted from as the connecting means (which is necessarily morerigid) is. located at points where resiliency is not required or. wherethe. used connection between one rhombic section and another wouldcompensate for any resiliency lost by providing such end connectinmeans';

Having describe my invention, what I claim as new and desire to secureby Letters Patent is: I

1. In a structure of the character indicated, a hollow cable havingapproximately abutt ng ends with convergin end portions, a wire havingdiverging en portions insorted in the converging end portions of thecable and brid ing the space between the ends of the cable and means forfixing the wire with relation to the end portions,

of the cable, which means is located in the different directions, a wireinserted in the end portions of the cable and bridging the space betweenthe ends of the cable, said wire and the end portions of the cable beingtwisted at a point removed from the ex-' tremities of the cable.

- In testimony that I claim the foregoing as my own, I have heretoaffixed my signa-. ture in the presence of two witnesses.
